Ervebo vaccine, that was recently seen in news, is primarily used to protect against which disease?
Ebola Virus Disease
Marburg Virus Disease
Yellow Fever
Lassa Fever
Ebola Virus Disease
The U.S. FDA approved the Ervebo vaccine for the prevention of Zaire ebolavirus in children aged 12 months and older as of 2026.
The Ervebo vaccine is a critical medical countermeasure used in the Democratic Republic of the Congo to combat outbreaks of Ebola Virus Disease (EVD). Recently, the scope of the vaccine was expanded by the U.S. FDA to include children as young as 12 months, whereas it was previously restricted to individuals aged 18 and older. While effective against the Zaire ebolavirus, it does not provide protection against other species like the Bundibugyo virus. The vaccine utilizes a live-attenuated vesicular stomatitis virus vector to trigger an immune response.
Vaccine Name: Ervebo (Ebola Zaire Vaccine, Live)
Target Virus: Zaire ebolavirus
Age Indication: 12 months of age and older
Manufacturer: Merck (known as MSD outside the US and Canada)
A is correct тАФ Ervebo is a single-dose vaccine specifically approved for the prevention of disease caused by the Zaire ebolavirus species.
Remember that Ervebo is highly specific; it protects only against Zaire ebolavirus, much like how specialized vaccines in the past were tailored to specific strains of influenza or polio.
